I own a shopbot prt standard 4x8 i want to fit proximity limitswitches on the x and y rails using mechanical contact switches can any advise me about how to go about wiring these switches to the machine? thanks

1. Buy good switches designed for dirty/wet industrial use (IE: Honeywell microswitch).

2. Don't use dry use, light duty electrical/electronic switches.

3. Machine wiring depends on the machine control/controller. Insufficient information to provide specific instructions.

i want to fit proximity limitswitches ...... using mechanical contact switches

Proximity switches do not have mechanical contacts.
If you are looking at true proximity type, there are a few configurations, DC, AC, AC/DC, three wire, two wire.
For the three wire there are sink or source type.
Selection depends on the interface used or required.

proximity limitswitches..... using mechanical contact switches

I suppose it would be possible to claim that a magnetic reed switch is a proximity switch with mechanical contacts. Provided the machine was not going to be creating particles or dust from a ferromagnetic material they could be a good way to get a combination of durability, dirt proof and electrical simplicity at a low cost.

Good Point.
I'm so used to working with Hall effect.
